IMPROVEMENT IN PEEDING-ATTAGHMBNT PGR COTTON-GINS.

TO ALL WHOM IT MAY CONCERN:

`Be it known that I, S. Z. HALL, of Camden, in the county of Camden, andState of New Jersey, have invented certain new and useful Improvementsin Cotton-Gins; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, making a portion of this specifcatiom-in which-Figure 1 is a side elevation of a cotton-gin constructed according to myinvention. Figure 2 isa plan or top view of the same. Figure 3 is adetached sectional view of a portion of the same. Similarletters ofreference indicate corresponding parts in all the figures. Y Thisinvention relates to that class of cotton-girls in 'which a rotatingtoothed cylinder is employed to convey the cotton bres to theginning-saws; and it consists in a feeding-cylinder constructed of wirecloth or other equivalent reticulated material, and furnished withsuitable teeth, in such manner that as the cotton is` passed vto the'saws the dust and dirt contained therein are allowed to fall throughtheA interstices of the wire cloth cylinder into the interior thereof,the cotton being greatly improved. in'quality by the removal of suchimpurities therefrom. The invention further consists in so arranging anadjustable pulley in relation'with the belt that drives the ginning-sawsand the belt that operates the feeding-cylinder, that any desiredtension of either or both of the said belts may be secured by simplychanging the position of the aforesaid pulley, The invention furtherconsists in so arranging a lever in connection with the pawlwhichactuates the rollers by which the cotton is conveyed to thefeeding-cylinder and with the breast of the gin, that the operation ofthe aforesaid lever simultaneously elevates the said breast and stopsthe motion of the rollers, whereby all dangei` of clogging the machine,bythe act of stopping the operation thereof, is effectually prevented.The invention further consists ina novel arrangement of parts foroperating the feeding-cylinder, the ginning-saws, and brushingcylinder,whereby great eiliciency of operation and simplicity of construction aresecured.

To enable others to understand the construction an d operation of myinvention, I will proceed to describe it with reference to the drawing.l

Situated transversely in the forward end of a suitable box or casing, A,is the feeding-cylinder B, the construction of which will presently befully explained, and which is supported upon a shaft, a, one end ofwhich extends through one side of the casing A, and is furnished with aspur-wheel, b, which gears into a pinion, c, formed upon or attached tothe inner side of a pulley, d, and situated underneath theaforesaidspurwheel Z2.` The bottom of that portion of the casing A back ofthe'cylinder B is composed of cylindrical rollers e, the shafts of whichare connected at one end by spur-gearing, as shown at a I2 in iig. 2, insuch manner that a movement communicated to one of the said rollers willbe communicated to all the others, the said rollers receiving anintermittent rotary motion by means of a ratchetwheel,f, secured to oneend of the shaft of one` of them, and acted upon by a pawl, g, pivotedto the lower end of a vibrating-lever, C, which may be pivoted upon theend of the shaft of one of the other rollers e, and the upper end ofwhich is provided with a longitudinal slot, C', through which is passeda crank-pin or wrist, d', attached to and projecting out from thespurwheel b, in such manner that the rotation of the cylinder Bcommunicates a vibratory motion to the leverC, and consequently worksthe pawl g to operate the ratchet-wheel f. In order to prevent anyretrograde movement of the aforesaid rollers, two pawls, y L, are placedin rear of the ratchet-wheelf, asshown in fig. 2, in such manner as tokeep the said ratchet-wheel from turning backward. D represents a bentlever, which is. secured upon the end of a transverse shaft, 7i, whichworks in suitable bearings underneath the casing A, the lower portion ofthe said lever being bent or curved back underneath theforwardly-projecting arm z' ofthe pawl g, as snown in fig. I. Securedupon the same shaft i as the lever I) is a downwardly-projecting arm, j,which is connected by a rod or link, k, with the breast E of the gin,the said breast being hinged at its upper end, as shown at m, in iig. 1,and being of any ordinary or suitable construction. By pushing forwardthe upper arm of the lever D the lowerA arm thereof will be caused tolift the forward end of the pawl g, thus 'depressing the rear endthereof and bringing it away from the ratchet-wheel f, and stopping themovement of the rollers e', simultaneously with which the arm j drawsback the breast E, thus tilting or raising the same and bringing it iaway from the ginning-saws, as requiredl when the operation of themachine is stopped, in order to prevent any liability of clogging thesame. The aforesaid saws are located within a suitable chest or case, F,situated for. ward of the casing A, and lower than the same, and areplaced upon a transverse shaft, one end of which is shown at n, and isfurnished with a pulley, r. G and I indicate two band-wheels which aresituated at one side or end ofthe gin-stand F. The ginning-saws aresecured upon the shaft of the band-wheel G, and to one or the other ofthe said band-wheels a rotary motion is communicated by any suitablemeans. These band-wheels are connected by a band, J, the lower side orportion of 'which passes over and upon the upper side of the pulley, r,and thus communicates a rotary motion to the shaft thereof, andconsequently to the brushing-cylinder which is situated npon the saidshaft. K indicates a grooved pulley which is pivoted in a stirrup, L,which is attached to a supporting standard, M, by means of a pin, s,which projects from its upper end, and which, after being lpassedthrough avvertical slot, m', in the aforesaid standard, has screwed uponit a nut, a', whereby is rigidly attached to the said standard. Thisgrooved pulley bears upon the upperportion of the band J, and isfurthermore connectedowith the pulley l by a suitable belt, u, so thatit operates not only as a friction-pulleyfto increase the tension of the,band J, which operates the ginning-saws and the brushing-cylinder, butalso to communicate the required rotary motion to the feeding-cylinderB; the pin s and the nut n enabling the aforesaid grooved pulley to beadjusted either to increase or diminish the pressure thereof upon theband J, or to tighten or loosen the belt u, as may be required. N showsapivoted apron situated in front of thefeeding-cylinder B, and designedto facilitate and secure the proper passage of the cotton from theaforesaid feeding-cylinder -to the breast and gnning-saws. The cylinderB is constructed as follows: Two circular heads c are connected by anannular series of longitudinal bars, w, and placedupon and around thesebars w is a covering, x, of wire cloth which constitutes the sides ofthe cylinder. Secured in each of the bars wis a row of outwardlyradiating teeth, z.

vThe unginned cotton being placed in the rear portion of the casing A,behind the feeding-cylinder B, the machine i's set in motion by themeans hereinbefore described, andthe intermittent movement of therollers e feeds the cotton forward-so that 'it is caught up by the teethof the cylinder' and carried upward and over the same, and thencedownward between the breast E and the ginning-saws. ,Asl thecotton isthus carried over the cylinder B the dust and dirt contained therein`arc caused to separate therefrom, and fall by their own gravity throughthe interstices of the wire-'cloth sides of the said cylinder B into theinterior of the same, thus eifectually cleansing the cotton therefrom,and materially improving the quality of the same.

Vhat I claim as new, and desire to secure by Ictters Patent, is-

1. '.lhe reticulated toothed feeding-cylinder B, constructed andoperating substantially as herein set forth, for the purpose specified.y j

2. The combination of the adjustable pulley K with the belt u whichoperates the feeding-cylinder, and the belt or band J which operates theginning-saws, in such manner that the tension of the said belts may beadjusted or regulated by changing the position of the aforesaid pulley,substantially as herein set forth.

3. So arranging the lever D, in relation to the pawl g, and inconnection with the breast E,that the same moi'ementofthe lever whichraises the breast shall simultaneously stop the movement of thefeeding-rollers e, substantially as herein set forth.

1 1. The belts u and J, operating in connection with the' pulley K, andarranged to aetuate the feedingcylinder, ginning-saws, andbrushing-cylinder, substantially as herein set forth.
